Description
662064-L21 HPE Intel Xeon E5-2670 — Server Processor
The HPE Intel Xeon E5-2670 (model 662064-L21 / part 662064-B21) is a high-performance server CPU engineered for enterprise-class compute, virtualization, and database workloads. Built on Intel's Xeon E5-2600 family, this 8-core, 16-thread processor offers a balanced mix of clock speed, cache, and platform bandwidth optimized for HPE ProLiant systems.
Primary specifications
- Manufacturer: HPE
- Model / Part Number: 662064-L21 / 662064-B21
- CPU Series: Intel Xeon E5-2600
- Cores / Threads: 8 cores / 16 threads
- Base Clock: 2.6 GHz
- Max Turbo: up to 3.3 GHz
- Smart Cache: 20 MB
- QPI Transfer Rate: 8 GT/s
- Lithography: 32 nm
- TDP (Thermal Design Power): 115 W
- VID Voltage Range: 0.60 V – 1.35 V
- Socket Supported: FCLGA2011
Performance characteristics
Designed for multi-threaded server applications, the E5-2670 delivers strong throughput for compute-dense tasks. The combination of 8 physical cores and 16 logical threads (via Hyper-Threading) enables efficient parallel processing, while a 20 MB Smart Cache reduces memory latency and accelerates data-intensive routines.
Key performance advantages
- High multi-core throughput for virtualization hosts and containerized environments.
- Turbo Boost to 3.3 GHz for bursty single-threaded workloads and lower-latency response.
- Large on-die cache to accelerate database queries, transaction processing, and analytics.
- Robust QPI interconnect (8 GT/s) for fast processor-to-processor and memory subsystem communication.
Platform compatibility & supported systems
This processor is validated for use in specific HPE ProLiant platforms and blade servers. Confirm platform compatibility before purchase or installation.
Common compatible systems
- HPE ProLiant BL460c G8 (blade server)
- HPE WS460c G8
- Other FCLGA2011 socket-compatible HPE ProLiant Gen8 systems (verify firmware and BIOS support)
Compatibility notes
- Always check server firmware/BIOS level for E5-2600 series support.
- When upgrading, match TDP and voltage ranges to existing system cooling and power delivery.
- Mixing different CPU steppings or frequencies in the same chassis may force lower clocks—follow vendor guidance.
Thermals & power
With a TDP of 115 W, the E5-2670 requires appropriate cooling and power provisioning. The VID voltage window (0.60–1.35 V) and thermal envelope make it suitable for dense rack deployments when paired with compatible HPE heatsinks and chassis cooling designs.
Thermal best practices
- Use HPE-specified heatsinks and airflow configurations for BL/WS chassis.
- Ensure chassis fans and ambient temperature comply with HPE operating guidelines.
- Monitor CPU temperatures after installation—thermal throttling will reduce performance if cooling is inadequate.
Ideal use cases
The E5-2670 is suited to a variety of enterprise workloads where strong parallel processing and cache performance are required.
- Virtualization hosts (VMware, Hyper-V, KVM)
- Database servers (OLTP/OLAP light-to-medium scale)
- Application servers and middleware
- High-performance computing nodes for parallel jobs
- Web farms and caching layers
Upgrade & replacement guidance
When planning an upgrade, consider the entire platform: socket compatibility, memory population rules, BIOS/firmware versions, and power/thermal headroom. The E5-2670 is an excellent drop-in upgrade for systems designed for the E5-2600 family, but always validate with HPE compatibility documentation.
Relative benchmarking and real-world throughput
When creating product content, avoid unverifiable or vague benchmark claims. Instead, provide relative expectations: purchasers should expect multi-threaded throughput that approaches modern mid-tier CPUs of its time, but with lower single-threaded performance compared to later Xeon families. Use wording such as “suitable for medium-density virtualization and web tiers” or “offers strong multicore throughput for legacy HPE platforms.” Include notes about how memory bandwidth and storage I/O will significantly affect real-world performance.
Performance optimization tips
- Populate all memory channels to take advantage of the CPU’s memory architecture.
- Use balanced CPU and memory pairings for virtualization hosts (avoid overcommitting CPU and memory without testing).
- Match cooling and power delivery to the server’s design; running near or above TDP without adequate cooling can thermal-throttle the CPU.
- Keep firmware and BIOS up-to-date on HPE systems to ensure optimal platform-level performance and stability.
Thermal design, power considerations, and reliability
Understanding the 115 W TDP
The 115 W Thermal Design Power rating indicates the thermal envelope the server chassis and cooling system must accommodate. For HPE ProLiant machines that accept the E5-2670, verify that the server's thermal profile and power supplies are rated for processors of this TDP class. When selling this processor, provide guidance on required or recommended heatsinks, fan assemblies, and thermal paste procedures to maintain reliability.
Power and redundancy
Power consumption at scale can impact rack planning and energy budgets. For data centers still operating Sandy Bridge-EP servers, list typical per-rack power expectations and suggest power redundancy approaches (dual power supply configurations, UPS sizing). Buyers appreciate practical advice: power draw depends not only on TDP, but also on workload, CPU frequency states, and the power characteristics of the rest of the system (disks, GPUs, NICs).
Compatibility with HPE platforms and part interchangeability
HPE ProLiant models and supported configurations
Clear compatibility guidance reduces misorders. The 662064-L21 part is intended for HPE ProLiant systems of the Gen8 era and similar platforms using the FCLGA2011 socket. When describing compatibility, include examples of server families (e.g., ProLiant DL, ML, and BL ranges) and advise shoppers to confirm server-specific CPU support lists or HPE QuickSpecs before purchase. Provide a short checklist buyers can follow to confirm fitment:
Compatibility checklist
- Confirm server model supports Intel Xeon E5-2600 series processors.
- Verify socket type FCLGA2011 and bios/motherboard microcode support for E5-2670.
- Ensure power and cooling in the chassis meet 115 W TDP requirements.
- Check that the server’s firmware (BIOS/iLO) is updated to versions that explicitly list E5-2670 support.
Commercial positioning and pricing guidance
Value proposition for buyers662064-L21 HPE Intel Xeon E5-2670 Processor
Position the 662064-L21 E5-2670 as a cost-effective, proven solution for extending the life of HPE ProLiant Gen8 servers and for organizations that require reliable multi-core performance without the premium of newer architectures. Emphasize lower acquisition cost compared to modern Xeon Scalable CPUs while noting limitations in power efficiency and single-threaded performance.
